Summary
Improving email deliverability from GSuite when sending 1-to-1 emails and encountering spam issues requires a multi-faceted approach. It starts with understanding the limitations of Google Postmaster Tools (GPT), which only provides insights from Gmail's perspective. Crucially, avoid sending unsolicited emails and identify any patterns in spam placement across different mail providers. Ensure a proper setup of SPF, DKIM, and DMARC records, verifying they are valid and include all sending sources. Review sending practices, ensuring you are not sending a mix of email types (support, service, cold) from the same domain. Warm-up new IPs gradually, maintain a clean email list, and create engaging content while avoiding spam trigger words. Actively monitor and manage your sender reputation, setting up feedback loops with ISPs and optimizing email preview text. Consider segmenting your lists and promoting recipient engagement to signal value to mailbox providers. For high-volume senders, evaluate switching to a dedicated IP address and ensure you have a valid reverse DNS (PTR) record.

Improving email deliverability from GSuite for 1-to-1 emails involves several key strategies. Firstly, understanding Google Postmaster Tools (GPT) is important, recognizing its limitations as it only reflects Gmail's perspective. Avoiding unsolicited emails and identifying common spam filters among affected recipients can help pinpoint issues. It's crucial to ensure emails are not marked as spam because of content, poor sending practices, or domain reputation, rather than just IP addresses. Warming up IP addresses, cleaning email lists, and creating engaging, high-quality content are essential. Avoiding spam trigger words, implementing authentication standards (SPF, DKIM, DMARC), setting up feedback loops, encouraging recipient engagement, optimizing preview text, and considering a dedicated IP address for high volumes are also crucial components of a successful deliverability strategy.

Improving email deliverability from GSuite relies heavily on proper configuration of email authentication methods. Correctly setting up SPF records, including all authorized sending sources like GSuite, is essential to prevent emails from being marked as spam. Implementing DKIM signing adds a digital signature, verifying email authenticity and increasing trust with receiving mail servers. Establishing a DMARC policy instructs receiving servers on handling emails that fail SPF or DKIM checks, with 'reject' or 'quarantine' policies improving domain reputation. Finally, ensuring your sending IP address has a valid reverse DNS record (PTR record) that points back to your domain is important, as a missing or incorrect record can raise suspicion and negatively impact deliverability.
Key findings
- SPF Configuration: Correct SPF record setup is crucial; include all authorized sending sources, including GSuite.
- DKIM Signing: Implementing DKIM signing verifies email authenticity and increases trust with receiving mail servers.
- DMARC Policy: Setting up a DMARC policy with 'reject' or 'quarantine' can improve domain reputation.
- Reverse DNS Record (PTR): A valid PTR record for the sending IP address is essential for deliverability.
Key considerations
- SPF Accuracy: Regularly review and update SPF records to include all authorized sending sources to avoid deliverability issues.
- DKIM Implementation: Ensure DKIM signing is properly implemented to add a digital signature to your emails.
- DMARC Enforcement: Consider the impact of implementing 'reject' or 'quarantine' policies with DMARC and monitor for any unintended consequences.
- PTR Record Verification: Verify that the PTR record for your sending IP address correctly points back to your domain.
